Our set lets pre-k through second-grade students set up a course of ramps, pendulums, hammers, switches and more…then drop a ball onto the tracks and go for the goal box! After each test run, kids will fine-tune the placement, distance and angle of each piece—getting firsthand practice with STEM concepts such as gravity, force and momentum! Packed with super-durable plastic pieces, the set is perfect for open-ended building—or kids can use the leveled challenge cards to create a variety of different courses from scratch! Set comes with 67 pieces, plus 6 balls, 10 challenge cards and a guide. The tracks measure 12\" in length.","brand":"Acme","offers":[{"title":"4 yrs. - 7 yrs. \/ Pre-K - 2nd gr.","offer_id":48607578063097,"sku":"US-2355-4-YRS-7-YRS-PRE-K-2ND-GR","price":30.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0817\/4223\/3849\/files\/000852-create-a-chain-reaction-stem-kit-pre-k-gr-2-master-set-01-7638fe5c.webp?v=1782720338","url":"https:\/\/lakeshorediscount.com\/products\/create-a-chain-reaction-stem-kit-pre-k-gr-2-master-set-pp566","provider":"Lakeshore outlet shop","version":"1.0","type":"link"}
